Science Instruction for Students With Learning Disabilities: A National Survey of Elementary Special Education Teachers
Elementary students with learning disabilities (LDs) often have limited opportunities to learn science, and little is known about how special educators engage in science instruction. This study drew on a nationally representative survey of elementary special education teachers to describe their roles, preparedness, time allocation, and perceived barriers. Most teachers reported minimal discipline-specific preparation and felt less prepared to tea…
Purposeful Practice Opportunities: How Guided and Independent Practice Informs Number Sense Development
Although practice is essential for academic development, questions remain regarding how much and what kinds of practice best support early learners. To examine the role of practice in developing mathematical proficiency, we analyzed rates of guided and independent practice opportunities provided in a kindergarten mathematics intervention for 880 students with mathematics difficulties (MD) across 255 groups. Results indicate that (a) students’ ini…
The Impact of Instructional Guidance on Science Learning in Second-Grade Classrooms
The appropriate level of instructional guidance for students to acquire a deep understanding of the disciplinary core ideas, crosscutting concepts, and science and engineering practices outlined in the Next Generation Science Standards remains ambiguous. To shed light on this important topic, we tested two distinct science programs in a cluster randomized controlled trial involving 11 second-grade classrooms and 185 students. Holding constant con…
Inquiry‐Based Science Instruction for Students With Disabilities: A Systematic and Meta‐Analytic Review
Developing scientific literacy is necessary for students with disabilities (SWD) as it supports the ability to create solutions to real‐world problems and understand current events, and it strengthens critical thinking, problem‐solving, and complex communication skills. The purpose of this systematic review and meta‐analysis was to evaluate extant literature on inquiry‐based science interventions for SWD in service of developing scientific practi…
Teacher Professional Development and Student Mathematics Achievement: A Meta-Analysis of the Effects and Moderators
An essential element for increasing student mathematics achievement is providing teachers with professional development (PD) aimed at the design and delivery of high-quality mathematics instruction. To date, however, there is a lack of consistent data on the efficacy of PD on student outcomes; moreover, there is a need to explore PD characteristics as moderators of student outcomes. The purpose of this meta-analysis was to synthesize the effects …
The Role of Instructional Design in the Delivery of Early Science Instruction
A critical tenet of education research is establishing what works. Another is exploring theorized mechanisms of change to help ascertain why academic programs work, for whom, and under which conditions. In other words, unpacking the black boxes of academic programs. This study explored the quality of teachers’ facilitation of (a) scientific investigations and (b) science discourse during and after the implementation of a systematic, explicit seco…
Do Mathematics and Reading Skills Impact Student Science Outcomes
Establishing validated science programs for students with or at risk for learning disabilities requires testing treatment effects and exploring differential response patterns. This study explored whether students’ initial mathematics and reading skills influenced their treatment response to a whole-class, second-grade science program called Scientific Explorers (Sci2). The original Sci2 study employed a cluster randomized controlled design and in…
National Survey of 4th and 5th Grade Science Education Teachers: Insights Into Instruction and Inclusion of Students With Disabilities
Elementary science education, particularly in the 4th and 5th grades, is essential for setting the foundation for lifelong science learning, fostering critical thinking, and preparing students for success in science, technology, engineering, and mathematics (STEM) fields. This stage is especially critical for students with disabilities, as achievement gaps between them and their peers emerge during elementary school. Despite this importance, litt…
Examining the relations between interventionists' use of classroom management and student mathematics gains within a Tier 2 kindergarten mathematics intervention
Effective classroom management is critical to supporting student learning and success in school. However, little research has focused specifically on the impact of classroom management on student mathematics achievement, especially in the early elementary grades or in a small group (i.e., Tier 2) context. To address this need we investigated the relationship between classroom management and student mathematics achievement within the context of RO…
Motivational interviewing for students in school settings: A meta-analysis
Measuring Instructional Interactions During Reading Instruction for Students Receiving Intervention in Middle School
More than two-thirds of middle school students do not read proficiently. Research has shown that targeted interventions using explicit instruction methods can improve reading outcomes for struggling readers. A central feature of explicit instruction is the systematic implementation of instructional interactions, but it is not clear what specific instructional interaction practices lead to stronger outcomes for middle school readers. This study us…
Proficiency With Number Concepts and Operations: Replicating the Efficacy of a First-Grade Mathematics Intervention
Conceptual replications are part and parcel of education science. Methodologically rigorous conceptual replication studies permit researchers to test and strengthen the generalizability of a study’s initial findings. The current conceptual replication sought to replicate the efficacy of a small-group, first-grade mathematics intervention with 240 first-grade students with mathematics difficulties in a new geographical region. Participating studen…
Intensifying Instruction to Address Treatment Resistance to Early Mathematics Interventions
A Synthesis of the Conceptualization and Measurement of Implementation Fidelity in Mathematics Intervention Research
In intervention studies, high rates of implementation fidelity are important markers of a study’s success; however, the definition of implementation fidelity is both complex and dynamic. In this synthesis, we examined the dimensions of implementation fidelity measured and reported in 99 studies in which researchers utilized a mathematics intervention for elementary students (i.e., Grades 1–5). We examined implementation fidelity following recomme…
Examining Interactions Across Instructional Tiers: Do Features of Tier 1 Predict Student Responsiveness to Tier 2 Mathematics Intervention
High-quality Tier 1 instruction is frequently conceptualized as the “foundation” for other tiers of intervention within multitiered systems of support (MTSS) models. However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness. The purpose of this study was to examine Tier 1 predictors, or “quality indicators,” of differential responsiveness to Tier 2 mathematics intervent…

Efficacy of a Second-Grade Science Program: Increasing Science Outcomes for All Students
This study, which was reviewed through the Registered Report process, examined the initial efficacy of the Scientific Explorers program (Sci2) on second-grade students’ science achievement. Sci2 is grounded in the growing body of empirical research on science instruction, embedding principles of explicit instruction within a guided inquiry-based design framework. Eighteen second-grade classrooms were randomly assigned to treatment or control cond…
Using Direct Observation to Document “Practice-Based Evidence” of Evidence-Based Mathematics Instruction
Implementation of evidence-based practices (EBPs) is paramount to students’ development of mathematics proficiency. This study investigated “practice-based evidence” of interventionists’ actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a federally funded efficacy trial involving a Tier 2 first-grade mathematics intervention to examine whether the quantit…
Kindergarteners at Risk for Severe Mathematics Difficulties: Investigating Tipping Points of Core Mathematics Instruction
A concerning number of students enter kindergarten facing an intractable variation of mathematics difficulties (MD). This study investigated the impact of an explicit, core kindergarten mathematics program on the mathematical outcomes of kindergartners who demonstrated risk for severe MD at kindergarten entry and examined whether these students improved from a category of high MD risk (i.e
